Uh Yes, The only way it would be different is if he or someone else changed his or their default prints.
Err, mitterdoo specifically said it was not that print.
OP is either lying or needs to get his eyes checked; there is no such print.
There were bugs before of shadows rendering text from FireFox upon surfaces, but it's really unlikely that this is something similar; OP would have probably noted if it was something he recognized.
